Summary of work:
The current need for light weighting requires the development of new materials that meet the targets while still having desired mechanical properties. The typical development-to-deployment for new materials takes about 20 years; To fast track this process, a new set of computational tools need to be developed. This requires a thorough understanding of the material behavior and the factors that govern the behavior at multiple scales. My work focusses on analysis of material response of high strength aluminum alloys, advanced high strength steel as well as magnesium alloys and use it in the development of new physically based models using crystal plasticity. These can then be used in conjunction with other techniques, like ab-initio calculations, to bridge the scale or other methods, like cellular automata and Monte-Carlo methods, to develop through processing models, both of which are my interest areas. I also work on developing representative synthetic microstructures that capture the underlying relevant statistics.

Summary of work:
The mathematical modelling of material behaviour is a very effective way of reducing time and costs involved in optimizing manufacturing processes and components performance. In order to tailor materials for component level applications, multiscale models are powerful tools, since they can account for relevant microstructural features and include the effects of temperature and strain rate sensitivity.
As a material engineer, my main research interest is in the optimization of the performance (formability and crashworthiness) of light metals and composites, using tools such as multiscale modelling and advanced materials characterization.
My research is in collaboration with the automotive and aerospace industries, and I perform both modelling and experimental work on various forming processes for light metals, as well as crashworthiness of composite materials.
